I’m working on Ruby and IronRuby to use with Cucumber. What is the  
difference between installing gems and igems?

When I; for example; “gem install -rspec”, it works good.

But when I “igem install -rspec”, it always gives an Error:

ERROR: [http://rubygems.org/](http://rubygems.org/) does not appear to be a repository

ERROR: could not find a valid gem ‘rspec’ (\>= 0) in any repository

is there any way I could install igems?
